Roads in Derbyshire could turn icy early on Sunday morning, the Met Office has warned.

A spokeswoman for the weather experts said temperatures were due to drop to about -1C between 5am and 6am.

She said: "There's certainly a risk of a sharp frost that morning because we are expecting clear skies. Temperatures will be at their lowest between around 5am and 6am on Sunday morning so drivers should be wary."
